A Torquemeter would be more useful, if you want to check the regularity of the torque suring the work of the movement, but a power reserve?
Did you often see a power reserve on most of the Chronometers? ( Ok, there is a Lange RL with a power reserve, but I still don't get its interest ).
The most efficient Chronometers worked very well WITHOUT power reserve indicator.
Therefore, if you have 60 hours of autonomy, it is long enough to not worry about reminding if you have to wind your watch before it stops, and not too short to avoid seeing your watch stops.
As for the Red 10 Hs, I got what you said in your initial post... Let's say that I am always suspicious when I see the design team opting for such a configuration, on such a classic watch.
What were they thinking?
The " yes, we know, we will remove it " excuse doesn't convince me. If it was an hoenst explanation, then why not removing it from the start???
Best,
